'Mighty One' in the Bible

Therefore saith the LORD God of Hosts, the mighty one of Israel: Ah, I must ease me of mine enemies, and avenge me upon them.

The remnant, yea and the Posterity of Jacob, shall convert unto God the mighty one.

Thou shalt suck the milk of the Gentiles, and kings' breasts shall feed thee. And thou shalt know that I the LORD am thy Saviour and defender, the mighty one of Jacob.
